Description

The present invention relates to a new product conditioning rinse

  for the hair, which provides suppleness, shine, maneuverability, ruffle reduction and ease of styling and is easily removable without accumulation using conventional anionic alkyl ether-polyethenoxy sulfates schampers. The essential components of the present composition are a distearyl or di (tallow alkyl) quaternary ammonium compound, a C8-C18 alkanol, a C7-C17 alkyl amido (C2-C3 alkyl) -di (C 2 -C 3) alkylamine, a mineral oil, a cyclomethicone and

  propylene glycol in an aqueous medium.

  The phenomenon of adsorption on the hair of quaternary compounds whose molecules comprise long-chain fatty moieties is at the base of most

  conditioning product formulas for the hair.

  The fatty portion of the molecule that is strongly attached to the substrate acts as a lubricant. The lubricating action

facilitates disentangling.

  It has been found that hair treated with a fatty quaternary compound or a conditioning product containing a fatty quaternary compound and then washed with a conventional shampoo containing an anionic alkyl etherpolyethenoxysulfate (AEPS) have a deposit on their surface. This deposit is a combination product formed by the interaction of the anionic surfactant of the shampoo and the quaternary compound of the conditioning product. Thus, it is difficult to remove the cationic quaternary compound by conventional shampoos containing AEPS because of the formation of a cationic-anionic complex on the surface of the hair. This deposit is not easily removed by the surfactants of common shampoos and, by the repeated use of the shampoo and the conditioning product, the

  amount of this deposit or accumulation tends to increase.

  In the field of hair conditioning, the prior art abounds in conditioning compositions for the hair containing one or more of the components

  present compositions that are new and original.

  For example, US Pat. No. 4,275,055 discloses compositions containing stearamidopropyldimethylamine as a conditioning agent, and US Pat. Nos. 4,149,551 and 4,206,196 disclose conditioning articles comprising di (lower alkyl) dimethylchloride. ammonium or a fatty alcohol as a conditioning agent

  carried by a flexible substrate such as paper or other.

  In US Pat. Nos. 4,421,740 and 4,269,824 there is disclosed a composition wherein the combination of di (hydrogenated tallow alkyl) dimethyl ammonium chloride and cetyl or stearyl alcohol is used. U.S. Patent No. 4,436,722 discloses the combination of distearyl dimethyl ammonium chloride, cetyl alcohol and propylene glycol in hair conditioning compositions. US Patents Nos. 4,144,326 and 4,160,823 disclose similar compositions which include the combination of distearyl dimethyl ammonium chloride and propylene glycol, and US Patent No. 4,183,917 discloses a conditioning composition for hair which comprises the combination of distearyl dimethyl ammonium chloride, mineral oil, cetyl alcohol and propylene glycol. However, US Pat. Nos. 4,160,823, 4,436,722, 4,269,824 and 4,421,740 place a quaternary ammonium monoalkyl chloride equal to quaternary ammonium di (higher alkyl) chloride as active conditioning agent in their compositions and, therefore, depart from their teaching of the present composition which is original and specific to quaternary distearyl and di (tallow alkyl ammonium) salts because It has been found that the replacement of the two-higher alkyl quaternary compounds with a higher alkyl single quaternary compound in the present composition adversely affects its conditioning properties and the resulting conditioning agent is not completely removed by washing with shampoos containing AEPS, which

  creates a buildup of product conditioning on the hair.

  However, it should be noted that none of the above patents discloses a hair conditioner composition comprising a mixture of a quaternary ammonium distearyl or di (tallow alkyl) quaternary ammonium compound. C8-C18) - (C2-C3) alkyl-di (C1-C2-alkyl) amine, a C14-C18 alcohol, a mineral oil,

  cyclomethicone and propylene glycol as essential ingredients emulsified in an aqueous medium.

  It has been discovered that a hair rinse conditioning composition comprising admixing a distearyl-di (C 1 -C 3 alkyl) ammonium compound with a C 7 -C 17 alkylamido (C 2 -C 4) alkyl- C3) -di (C1-C20alkyl) -amine, a C1-C18 alkanol, a mineral oil, a cyclomethicone and propylene glycol dispersed in an aqueous medium, gives a stable composition having good conditioning properties, especially with regard to the body, the luster, ease of disentangling, the antistatic ca20 character (ruffling reduction) and the ease of styling the hair, and which is easily

removable without accumulation.

  Accordingly, it is an essential object of the present invention to provide a hair conditioning product which gives superior hair effects.

  packaging, flexibility and maneuverability, and has an antistatic effect and facilitates disentangling.

  Another object of the present invention is to provide a conditioning rinse composition for hair which is easily removable without accumulation.

  by common shampoos containing a detergent of the AEPS type.

  Another object of the present invention is to

  provide a rinse conditioning product for cheeks, which is stable and non-irritating, and can be applied daily after shampooing.

  Yet another object of the present invention is to provide a rinse conditioning product for

  hair, which communicates a strong shine to the hair.

  Another object of the present invention is to

  provide a rinse-conditioning product for chewing, the concentration of essential active ingredients is minimal.

  Other purposes, advantages and novel features of the present invention will be set forth in the

  following description or will become apparent to the skilled artisan in the practice of the present invention.

  In order to achieve the above and other objects in accordance with the present invention, the novel hair rinse conditioning composition consists essentially of about 0.5% to 2.5% by weight of a composed of distearyl or di (hydrogenated tallow alkyl) di (C 1 -C 3 alkyl) -quaternary ammonium, about 0.5% to 2.0% by weight of a C 7 -C 17 alkylamido ( C2-C3 alkyl) -di (C1-C2 alkyl) amine, about 1% to 10% by weight of a C1-C18 alkanol, about 0.2% to 1.5% by weight of an oil-mineral, about 0.1% to 2% by weight of cyclomethicone and about 0.2% to 2% by weight of propylene glycol, in about 80% to 97.5% by weight of a

  aqueous vehicle. The final product is in the form of an emulsion and its pH is about 4-6, preferably 4.5-5.5.

  In a preferred aspect, the present invention relates to a stable conditioning composition for the hair, which is easy to remove without undesirable buildup on the hair by means of a shampoo containing a detergent of the AEPS type, whose pH is about 4.5 to 5.5, and which consists essentially of, by weight, about 0.7% to 2% of a quaternary ammonium compound selected from quaternary distearyldimethyl ammonium chloride and di (hydrogenated tallow alkyl) quaternary ammonium dimethyl ammonium chloride, about 0.75% to 1.5% of C 13 -C 17 alkyl aminopropyl dimethyl amine, about 1.5% to 4% of cetyl alcohol or stearyl alcohol, approximately 0.3% to

  1.0% mineral oil, about 0.2% to 1% cyclomethicone and about 0.4% to 1.5% propylene glycol, emulsified in 89% to 96.2% water.

  The conditioning compositions described are opaque liquids and stable at room temperature.

  In addition, these compositions are stable at 5 ° C. and from 38 ° C. to 48 ° C. These compositions are considered to be oil-in-water emulsions, the two cationic compounds being the

emulsifying agents.

  As mentioned, these compositions contain harmless, non-irritating chemicals for the

  skin, non-toxic and effective to improve the maneuverability of the hair.

  It is believed that the good conditioning properties are imparted to the hair when the composition is applied thereto with or without subsequent rinsing due to the use of the essential mixture of conditioning agents, namely the distearyl or di (alkyl) salt. hydrogenated tallow) -quaternary ammonium, (C7-C17) alkylamido (C2-C3) alkylamine, saturated C14-C18 alkanol and mineral oil. In addition, it is believed that the combined action of the aforementioned essential ingredients is responsible for the ease with which this conditioning mixture can be removed during normal washing with a common shampoo containing an AEPS type detergent. Also, the conditioning mixture produces balanced conditioning effects and gives the hair better luster than normally does the mixture of cationic conditioning compounds and said C14-C18 saturated alkanol. In addition, the mixture of cationic compounds serves as an agent

  emulsifying by giving the desired physical stability.

  In addition, it has now been discovered that the novel hair conditioning products of the present invention are more readily and easily removed by washing with a shampoo containing AEPS, hence

  negligible accumulation of product conditioning on the hair despite prolonged use. A comparison

  reason with other formulas confirms that this is an unusual and unexpected property of the present conditioning products. It has also been found that this rinse-conditioning product leaves hair strands brighter (cleaner) than when these locks are treated with other conditioning products or by shampoos which ordinarily contain anionic surfactants such as lauryl ether. sodium sulphate (LESS),

  triethylol ammonium lauryl sulfate (LSTEA) and sodium lauryl sulfate.

  Long-chain di-alkyl-quaternary ammonium salts which are one of the essential ingredients of the conditioning agent mixture have been used in the prior art as conditioning agents for hair. These are substantially water-insoluble surfactants, but can be made into stable aqueous dispersions at 4-8% concentrations. They are soluble in isopropanol, methanol and ethanol. In general, the appropriate cationic quaternary ammonium salts have the following formula: R4

1 - N

I II

L R2 | + 3

  wherein R1 and R2 are stearyl groups, R3 and R4 are each an alkyl group of 1 to 3 carbon atoms and X is an anion selected from chloride, bromide and methylsulfate. The term "stearyl groups" refers to commercially available quaternary ammonium distearyl compounds which contain about 95% by weight of alkyl groups corresponding to stearyl and also commercially available quaternary ammonium di (alkylated tallow) ammonium compounds of which the alkyl group is derived from a mixture of C14-C18 alkyl groups where the group predominates

  alkyl corresponding to stearyl. For example, salt of am-

  The commercially available quaternary monium sold under the trade name Arquad 2HT contains alkyl groups obtained by hydrogenation of fatty acids derived from tallow and which comprise 4% by weight of C14 alkyl, 31% by weight of C16 and C16 alkyls. % by weight of C18 alkyl. Thus, the appropriate quaternary ammonium distearyl ammonium compounds contain at least 60% by weight of alkyl groups corresponding to stearyl. Representative examples of suitable quaternary ammonium distearyl ammonium salts include distearyl dimethyl ammonium chloride, di (alkyl) chloride and the like.

  hydrogenated tallow) -dimethylammonium, distearyldiethylammonium bromide and distearyl dimethylammonium methylsulfate.

  The quaternary distearylammonium salts used in the present conditioning compositions can be supplied by a number of suppliers either in the form of a liquid or a paste at 25 ° C in a water-isopropanol solvent, or in the form of a solid. The preferred quaternary compounds are quaternary ammonium di (allykyl) ammonium chloride sold by Armak under the trade name Arquad 2HT as a 7475% active ingredient paste in aqueous isopropanol and whose groups The alkyl groups are 4% C14, 31% C16 and 64% C18 on a weight basis, as well as distearyl dimethylammonium chloride sold by Sherex Chemical Co. under the trade name Arosurf TA 100 in the form of a free flowing dry white powder whose alkyl groups are at 2.5% C16, 95% C18 and 2.5% C20 on a weight basis. The distearyl di (C 1 -C 3 alkyl) ammonium salt is used in an amount of about 0.5% to 2.5%, preferably 0.7% to 2%, by weight of the composition. The second ingredient of the conditioning mixture used in the conditioning compositions is also a cationic substance, namely a (C 7 -C 17) alkylamido (C 2 -C 3) alkyl-di (C 1 -C 2 alkyl) amine salt,

  who has been employed as a conditioning agent in

  positions of the prior art. Examples of suitable cationic amines include stearamidopropyldimethylamine, lauramidopropyl dimethyl amine, coconut alkyl amido propyldimethyl amine, palmitamidopropyl diethyl amine, myristamidoethyl dimethyl amine and stearamidopropyl diethyl ether. amine. (In the preceding list, the compounds are named after the alkanoic acid from which the amide is derived, for example, the stearamido group comes from the reaction of stearic acid with an organic amine but, in a more correct nomenclature. it would be called heptadecylamido because the amido group is a radical -C (O) N =). Preferred amines are (C 1 -C 17) alkylamidopropyl dimethylamines, and most preferred is heptadecylamidopropyl dimethylamine. The proportion of this (higher alkyl) amido- (lower alkyl) -di (lower alkyl) amine in the final composition is from about 0.5% to 2%, preferably 0.75% to

1.5%, by weight.

  In the conditioning compositions, the (C 7 -C 17) -alkylamido (C 2 -C 3) alkyl-di (C 1 -C 2 -alkyl) -alkyl is present in the form of an acid salt.

  is formed when the amino base is neutralized with a water-soluble acid to give the acid cationic salt.

  Acids suitable for neutralizing the cationic amine include citric acid, acetic acid, lactic acid, tartaric acid, gluconic acid, hydrochloric acid and phosphoric acid, acid, and the like. citric being preferred. The proportion used of the acid must

  be sufficient to obtain a composition having a pH of 4-6 and preferably about 4.5-5.5.

  In the conditioning product, the di (higher alkyl) ammonium quaternary salt and the alkylamidoamine salt are the main conditioning agents and are the emulsifying agents. In addition, the (C 7 -C 17) alkylamido (C 2 -C 3 alkyl) di (C 1 -C 2 alkyl) amine salt is effective in modifying the film of cationic material deposited on the hair so as to reduce at least the impression of heavy coating characteristic of di (higher alkyl) ammonium salts quaternary. Thus, the relative proportions of the two cationic compounds are bound in the range of 10: 1 to 1: 5, preferably 2: 1 to 1: 2, this ratio being that of the di (higher alkyl) salt.

  quaternary ammonium salt with alkyl amido amine salt.

  The third ingredient in the conditioning agent mixture is a C14-C18 alkanol. Since the preferred alkanols are obtained from fats and oils, these alkanols are often referred to as fatty alcohols.

  However, the alkanols prepared by synthetic methods are also satisfactory. Examples of suitable alkanols are 1-tetradecanol, 1-hexadecanol, 1-heptadecanol, 1-octadecanol and mixtures of C14-C18 alkanols obtained by hydrogenating fatty acids from tallow. The preferred higher alkanols are stearyl alcohol and cetyl alcohol. The proportion of C14-C18 alkanol in the conditioning composition is from about 1% to 10%, preferably 1.5% to 4%, by weight. In addition, the C14-C18 alkanol is normally the predominant ingredient in the conditioning agent mixture because it is

  present in the highest percentage. Typically, the weight ratio of C14-C18 alkanol to total cationic surfactants ranges from about 2: 1 to 0.75: 1. The C14-C18 alkanol is believed to act as a co-emulsifying agent, thicken the emulsion and stabilize the product.

  The essential final ingredient of the conditioning agent mixture is a mineral oil, another substance used in hair conditioning products of the prior art. Mineral oil is a homogeneous mixture of saturated aliphatic and alicyclic hydrocarbons derived from petroleum. The mineral oil is chemically and biologically inert and hydrophobic in nature. Mineral oil is available in various viscosities. The proportion of mineral oil in the conditioning composition is about 0.2% to 1.5%, preferably 0.3% to 1.0%, by weight. Normally, mineral oil is less than% by weight of the blend of the four conditioning agents

  and preferably less than 10% of the weight of this mixture.

  These small amounts of mineral oil tend to oppose the tarnishing effects of cationic surfactants by enhancing the shine of the hair and also act as a plasticizer for optional film-forming polymers when present in the skin.

  final composition. In addition, mineral oil helps reduce the amount of quaternary ammonium salt residue remaining on the hair after shampooing.

  Propylene glycol present as an essential component is a colorless, clear and viscous liquid which is hygroscopic and miscible with water in all proportions. Propylene glycol can enter the pillar shaft and remain there after rinsing. It is believed that the action of propylene glycol causes relaxation and swelling of the hair at the same time as it produces a humectant effect, i.e., it allows hair containing conditioning agents to retain their Humidity and flexibility between shampoos. The proportion of propylene glycol used in the final composition is about 0.2% to 2%, preferably 0.4% to 1.5%, by weight. Another essential component is a cyclomethicone which is a volatile cyclic silicone represented by the formula: ## STR2 ## wherein R is a C 1 -C 3 alkyl group or a phenyl group, preferably a methyl group, n is a number of 3 to 10, preferably 3 to 7, and the free valences of the oxygen and silicon atoms present at the ends

  of the chain are united together to form a structure

  cyclical ture. Suitable cyclic silicones are available as low viscosity liquids from a number of manufacturers, including General Electric Company. The most preferred cyclomethicones are decamethylcyclopentasiloxane (Silicone).

  Fluid SF 1202 from General Electric) and octamethyl cyclotetrasiloxane (General Electric Silicone Fluid SF 1173).

  Cyclic silicones are apolar, insoluble in water and miscible in all proportions in lower alcohols, aliphatic and aromatic solvents and solvents of the halogenated hydrocarbon type. This component facilitates the distribution of the conditioning agent mixture on the hair and the rapid spreading of the conditioner film on the hair. The proportion of volatile cyclic silicone in the conditioning composition is from about 0.1% to 2%, preferably 0.2% to

1.0%, by weight.

  The essential final component of the hair rinse conditioning composition is an aqueous medium consisting primarily of water. Since some of the distearyl-di (C 1 -C 3) alkylammonium salts may be provided in admixture with a C 2 -C 3 alcohol, for example isopropanol, the aqueous medium may contain a small amount of this C2 alkanol. C3. In addition, if desired, an additional C2-C3 alkanol may be added to the composition, particularly if the composition is marketed as a "foam". The proportion of the aqueous medium is in the range of 80% to 97.5%, preferably 89% to 96.2%, and more preferably 90 to 95.0%, of the weight of the conditioning composition. Optionally, the conditioning compositions may contain a water soluble nonionic cellulosic polymer as a thickening agent. Suitable cellulosic polymers are selected from hydroxyethylcellulose and hydroxypropylmethylcellulose, with hydroxyethylcellulose being preferred. Hydroxyethylcellulose is the product of the reaction of alkalicellulose and ethylene oxide, and these products are available in various viscosities. The viscosity is mainly a function of the viscosity of the cellulose used in the reaction. The degree of hydroxyethyl substitution per glucose unit is 1.4-1.5, the molar hydroxyethyl substitution is 1.5-3.0 and these hydroxyethylcellulose have an average molecular weight ranging from about 80,000 at about 900,000. Particularly preferred hydroxyethylcellulose is available under the tradename Natrosol 250 HR from -Hercules, Inc. The water-soluble hydroxypropyl methylcellulose has a methoxyl content of from about 25% to about 32%. % by weight and a hydroxypropyl content of between about 2% and 10%, preferably 2% and 7%, by weight. Here again, the chain length of the cellulose used in the reaction can be determined to obtain a molecular weight such as the viscosity of a

  2% solution in water is in the range of from 10 to 20 mPa.s at 5000 mPa.s, preferably from 50 mPa.s to 4000 mPa.s.

  By acting on the viscosity, these cellulosic polymers give the composition the stability to aging. The composition retains its viscosity without becoming lighter or thicker. In addition to stabilizing the viscosity of the aqueous conditioning composition, the cellulosic polymer tends to form a film on the hair to which the conditioning agent mixture is applied, forming hydrogen bonds with the cationic surfactants. The proportion of the nonionic cellulosic polymer, if present, is from about 0.25% to 2.5%

  preferably 0.5% to 1.5%, of the weight of the conditioning composition.

  Another film-forming polymer that can be incorporated into the conditioning compositions together with the foregoing cellulosic polymer is a water-soluble nonionic polyvinylpyrrolidone. Polyvinylpyrrolidone (PVP) is available in a range of average molecular weights of about 10,000 to 360,000 and the type known in the trade as PVP K-30 having an average molecular weight of about 10,000 is preferred. Polyvinylpyrrolidone is available as a powder (containing about 95% polymer and 5% water) and as an aqueous solution. It is believed that the polyvinylpyrrolidone cooperates with the cellulosic polymer to form a transparent film on the hair, which helps maintain the shape of the hair, but is also smooth and supple so that it does not interfere with disentangling. The proportion of polyvinylpyrrolidone, if present, is from about 0.02% to 1%, preferably 0.05% to 0.5%, by weight of the final composition. However, the polyvinylpyrrolidone normally constitutes a minor fraction of the epoxide, i.e., about 4% to 15% by weight of the polymer blend, so that a smooth, substantially tack-free film is obtained. Proportions of polyvinylpyrrolidone exceeding 1% by weight give a film which is too rigid and sticky. The film formed by the combined action of PVP and the nonionic cellulosic polymer is also plasticized by the combination of

  propylene glycol and mineral oil.

  The conditioning compositions of the present invention may also contain conventional additive components such as dyes, perfumes, preservatives such as formaldehyde (Formalin) and optical brighteners such as Uvinul. Other optional components are urea and d-glucose in respective proportions of 1-2% and 1-3% by weight. The total weight of these optional additives does not normally exceed 5% of the weight of the composition and preferably does not exceed the weight of the composition, the proportion of the components

  individual cells being often 1% by weight or less.

  The hair conditioning product according to the present invention may be in the form of a pouring lotion or smooth cream. In addition, the final product may have any suitable viscosity that is suitable for the shape

  chosen final, for example a lotion to be poured, a thick or viscous lotion or a cream.

  The present conditioning compositions can be readily manufactured by simple blending methods. For example, a preferred method for preparing the present compositions comprises the steps of: dissolving propylene glycol, quaternary distearyl ammonium compound and pH adjusting acid (citric acid) in the formulated water weight under stirring. a temperature of 400C to 90 C to obtain a homogeneous aqueous solution; separately prepare a mixture of the remaining water-insoluble ingredients, namely C14-C18 alkanol, C7-C17-alkylamido (C2-C3alkyl) -di (C1-C2alkyl) -amine , mineral oil and cyclomethicone and heat this mixture to a temperature of about 70 C to 85 C; adding with slow stirring the mixture of water-insoluble ingredients to the aqueous mixture while maintaining the temperature in the range of 800C to 85C; cooling the resulting emulsion to a temperature of 35 C to -45 C with slow stirring; add, as appropriate, all other optional ingredients to the above mixture; and cooling the resulting composition to a temperature of 25 ° C to 30 ° C with slow stirring to form a stable, opaque emulsion having a pH in the range of 4 to 6. Any required pH adjustment is usually made during the cooling of an appropriate concentration of acid or hydroxide

alkali metal.

  When polymers are present, the cellulosic polymer is usually dispersed in water at a temperature of 80 ° C. to 850 ° C. before the series addition of propylene glycol, quaternary ammonium distearyl salt and acid. and the polyvinylpyrrolidone is dissolved

  in water and added to the product during the cooling step at 35 C-45 C.

  The following nonlimiting examples illustrate the present invention. In these examples, as elsewhere in this specification, the proportions of the various ingredients are by weight unless otherwise indicated.

  In Table 1 below are shown the wet disentangling properties and the ability to remove by shampooing based on sodium lauryl ether triethenoxy sulfate the conditioning hair rinse compositions of Examples 1-4. In the evaluation reported in Table 1, pre-washed locks of untreated European-type hair measuring 20 to 25 cm in length are wetted with water, treated with the conditioning composition to be tested, rinsed and dried. detangles, and then treated with an aqueous shampoo containing 10% by weight of sodium lauryl ether diethylenesulfate, rinsed and detangled. This treatment is repeated 3 times and 6 times to highlight the effects of multiple hair treatments. All the locks of hair are washed for one minute with the aqueous lauryl-ether-sulphate-sodium shampoo, rinsed with water at 40 ° C. for a minute and dried. In the test process, each wick is wetted with water at 40 ° C, wrung to dryness and treated with one gram of the conditioning composition to be tested which is penetrated into the wick 25 by working with fingers for a minute. Then, the wick is rinsed with running water at 40 C for one minute and an experienced hairdresser untangles it to evaluate the disentangling properties of the hair conditioning product. The packaged wick is then washed for one minute with said sodium lauryl ether diethylenesulfate shampoo by thoroughly penetrating the shampoo into the wick by working with the fingers for one minute to produce foam. The washed wick is rinsed with running water at 40 ° C. for one minute and the wick is disentangled to determine the wicking properties of the wick washed with the shampoo to evaluate the degree of removal by said shampoo. of the product conditioning to try. These same locks are treated three or six times with, alternatively, the conditioning product and the said shampoo, ending with the shampoo, to simulate what happens when the conditioning product is used regularly. The evaluation tests of the disentangling facility are performed as described above by six experienced hairdressers and the ease of disentangling is scored on a scale of one to five depending on the work required to pass the comb 10 into the wick. In terms of ease of wet disentangling, hair treated only with a conditioner (control conditioner) receives a score of five

  Those treated with the conditioning product of the invention are cleaner than those treated with the control after one and three shampoos. These results also show

  the specificity of the use of quaternaryl quaternary ammonium compounds (distearyl or hydrogenated tallow dialkyl) in the readily removable hair conditioning product of the present invention. More particularly, each of the compositions respectively containing a quaternary dicetyl- or dilaurylammonium salt engenders an accumulation of conditioning product on the hair treated after the shampoos (Examples 3 and 4).

EXAMPLE 5

  The importance of using quaternary distearyl ammonium salt as the main conditioning agent in the compositions of the invention is shown in Table II below, which gives results on the ease of wet disentangling of locks of hair which one gram of the example composition containing 0.75% by weight of one of the various conditioning quaternary agents is then treated, rinsed for one minute with running water at 40 ° C. and evaluated for ease of disentangling in the wet; after which the conditonné locks were washed for one minute with a shampoo of sodium lauryl ether-diethenoxy sulphate (10% of organic sulfate) and rinsed for one minute with running water at 1 ° C. and the washed and rinsed locks were evaluated. about the

  These results show that the cetyl, stearyl, tallow alkyl and lauryl trimethyl ammonium chlorides are not as good as the di (hydrogenated tallow alkyl) and distearyl dimethyl ammonium chlorides to achieve powerful conditioning as determined by the ease of wet disentangling. In addition, Table II shows that the C12-C18 monoalkyl ammonium quaternary salts accumulate to a greater extent after three cycles of treatment than the quaternary ammonium distearyl ammonium salts despite the fact that the distearyl compounds deposit in greater quantity

  with each conditioning treatment.

  In addition, the 0.67 value assigned to the control shampoo suggests that the wicks treated with the quaternary distearyl compounds are cleaner than the control wicks because the values 0.39 and 0.46 indicate that there is less residue on the wicks. treated locks only on those

control shampoo.

  The lowest conductive product accumulation on conditioned hair after repeated use is also confirmed by electrospectrochemical (ESC) measurements made on individual hair from wicks treated with various conditioning compounds for hair. As in Examples 1-5, pre-washed locks were treated with the conditioning composition to be tested, rinsed, washed with sodium lauryl ether diethylenesulfate shampoo and rinsed six times before drying and to examine them by means of an electrospectrochemical analyzer. In this analysis, the cationic conditioning agent deposition as well as the deposition of anionic sodium lauryl ether di-ethoxy sulphate are determined by the relative percentages of two chemical forms of nitrogen and sulfur which are observed on the surface of various hair samples. More precisely, sulfur exists in two chemical forms on the surface of the hair, namely SII and SVI, whereas the anonic sulphate contains only SVI. Thus, the deposition of anionic fate contains only S. Thus, the deposition of anionic sulfate on the surface of the hair is revealed by an increase in the SVI content relative to SII. Similarly, nitrogen exists in quaternary and non-quaternary forms. Table III below gives the results of ESC studies carried out on locks each treated with six conditioning-shampoo treatments with, alternately, one of the various conditioning agents listed, then a lauryl-ether-diethenoxy shampoo. sodium sulphate.

  It can be seen from Table III that the ESC analysis shows a quaternary ammonium chloride deposition only (samples E and F), which is in the form of an anionic-cationic complex according to the increase of SVI. compared to SII. Thus, ESC studies establish that it is in the form of an anionic-cationic complex that the accumulation on the hair of non-distearyl quaternary ammonium conditioning agents which are not washed off with a

  shampoo containing a surfactant of the anionic alkyl ether-polyethenoxysulfate type.

EXAMPLE 6

  The criticality of each of the six essential components of the novel rinse conditioner composition of the present invention is evidenced by wet disentangling ease tests, the results of which are shown in Table IV and which were performed with compositions corresponding to the composition of Example 1 from which has been excluded one or more of the essential components. The results of Table IV are obtained by the same evaluation test as in the preceding Examples, the values being given for a conditioning cycle and for
